Income should be the exponent. Lets say that the fine you pay on your n’th infraction within a 365 day period is
f = I f_0 exp( (I / I_0) (n - 1) )
where f_0 is some reasonable fraction of income for the first fine (say 0.1 %), I is your income, and I_0 is some appropriate modifier (say 100 k EUR / yr). That way, people with income I < I_0 pay an essentially flat fine until they reach very many infractions, while people with large incomes will reach massive fines very quickly.
That could bankrupt poor people. It needs to have some wealth or income component or it will never be fair
